Patented June 3, 1930 UNITED STATES PATENT OFFICE CHARLES DOLLACK, OF GLENDALE, LONG ISLAND, NEW YORK, ASSIGNOR TO THE JACOBS BROTHERS 00., INQ, OF BROOKLYN, NEW YORK, A CORPORATION OF NEW YORK SCALE Application filed May 14, 1927.

This invention relates to an improved scale.

It is an object of the invention to provide a device of this character including a counterweight in convenient association therewith, this weight being readily associated with the proper scale parts, the structure achieving this purpose embodying relatively few parts individually rugged and readily 1 constructed and operated with minimum effort.

It is a further object of the invention to provide an improved scale pan structure to prevent an accidental displacement of the pan while in use.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevation of a scale embodying the improved construction of the present invention;

Fig. 2 is a partly fragmentary plan view thereof;

Fig. 3 is a fragmentary elevation of a slightly different form of construction from that shown in the preceding figures; and

Fig. 4 is an end view of certain of the construction shown in Fig. 3.

In these views the numeral 5 indicates the scale base, which, in the present instance, by means of arms 6 and pivots associated therewith, rockingly supports a beam 7; this beam being connected to a yoke 8, to the lower end 4 of which a dashpot (not shown) may be Serial No. 191,298.

attached. In the present instance, one arm of the beam is extended in the form of a pair of graduated bars 9, with the graduations of each of which a weight 10 registers, these weights being mounted for sliding movement upon the bars.

The second arm of the beam suitably mounts a pan-supporting member 11 carrying at its upper end radially-extending arms 12, the ends of which are upstruck as at 13 to extend substantially at right angles to their bodies. Resting within these arms is a pan 14, the side walls of which are slightly inclined to bear against the upstruck endportions 13 of the arms 12. Due to the fact that the latter have a certain inherent resiliency, it will be appreciated that while the pan is readily removable from its position its accidental movement will be virtually precluded for the reason that the wedge fit will exist between the parts.

That end of the base 5 which underlies the bars 9 mounts a bracket 15 having at its upper end a plate formed with an opening 16 through which the extension 17 of the beam projects. This bracket also mounts a plate 18 formed with an opening through which the shank 19 of a bottle weight 20 extends, the shank mounting a washer 21 of suflicient- 1y large size that it may not pass through the opening of the plate 18, and the upper end of the shank terminating in a hook 22; the inner edge of which provides a bearing surface. The outer end of the extension 17 is forked as at 23, and extending between the arms of this portion is a pivot 24. As a consequence, the hook portion 22 may be disposed to extend over the pivot 24 as in Figs. 1 and 2; the weight 20 being thus free to suspend from the beam and exerting a minimum amount of friction when the latter rocks.

In the form of construction shown in Figs. 3 and 4 the beam extension 17 is provided with a laterally-extending hook shaped pivot overlying the opening of the plate 18, and the shank 19 of the weight terminates in an eyelet 26 for ready association w in the extension 25; it being observed that the eyelet or rounded end of the shank is su'f'cientiy la to prevent the same from slipping clear of he plate 18.

i 'hus, in botl of the illustrated embodiments the scale may be sed and the load weighed by means of the sliding weights. Under such conditions, the counterweight, in each instance, will be supported by the bracket 15, and accidental tachment oi the weight from the scale PilltS will be prevented. in operator, upon finding that it is necessary to attach the weight of the beam, may achieve this simply by moving the former upwardly to a point at which its supportin structure is z suspcnded by means of pivots or 2o.

Further, it a pan-supporting structure of the nature show-In is employed it will. be

nreciated that an operator will not displace the pan by striki the pan beiuo' supported e strained nst mc-vunent arms within which nests.

Thus, among others the objects of this invention have been accomplished, and since c ain changes may be made in the above construction, and diilerent embodiments of the invention could l e made, hout departing "from the scope thereof, it intended that all matter contained in the above description shown in the accompanying drawings shall be interpreted as illustrative and not in a hunting sense.

It is also to be understood that the following claims are intended to cover all of the neric and specific features of the inven than herein cescribed and all statements of the scope of the invention which as matter ot' language might be said to tall therebetween,
